It will be held March 4 to 6 at Sam Boyd Stadium, about 11 miles east of the Strip.

The tourney will feature teams from 16 countries -- from Argentina to Australia and from Fiji to France. Twelve of them, including Team USA, have qualified for the 2016 Olympics, which runs from Aug. 5 to 21.

The fast-paced matches last just 15 minutes -- two, seven-minute halves with a one-minute halftime. Instead of the 15 players per side in traditional rugby, or what's called union rugby, the teams field just seven players each.

“It’s played on the same size field of the traditional game,” Cornelius added. “It’s a very easy game for Americans to watch ... as it relates to soccer and basketball in finding space [to maneuver].”
